摘要 针对现有土工合成材料加固土工构筑物的缺陷,提出了端部卷轴式土工格栅加固方法,分析了该方法的作用原理及优点.以新建尾矿库尾矿堆积坝加固工程为背景,利用水平条分法和数值模拟,研究了端部卷轴式土工格栅用于尾矿堆积坝加固的可行性.结果显示,采用端部卷轴式土工格栅加固后,不仅使尾矿坝的稳定性提高14%-17%,而且能改变坝体应力场的分布,使其朝着有利坝体稳定的方向变化. In order to avoid the shortcomings of current reinforcement method for geo-synthetic materials, a type of reinforcement method, named an end scroll geosynthetics that both the start port and the end port of geosynthetics were rolled in reinforcement, was introduced. Its function principle and advantages were also analyzed. And with the new tailings dam reinforcement project, the feasibility of using the reinforcement method of end scroll geosynthetics in the railings dam was analyzed by horizontal slice method and numerical simulation method. The results show that after using the reinforcement method of end scroll geosynthetics, not only the stability can be increased by 14% ~ 17% , the stress distributions are also changed toward the favorable direction to darn stability.
